Manuscript Summary: 15th century Pontifical. The ceremonies are represented as full page miniatures with ornamental initials, marginal decorations and several lines of text on the model of books of hours; in the text there are many colorful borders and ornamental initials, often with depictions of the liturgical objects mentioned in the text. In addition to the frequently recurring coat of arms of Melchior von Lichtenfels, Archbishop of Basel (1554-1575), there is the coat of arms of Charles de Neufchâtel, Archbishop of Besançon (1463-1498; visible on f. 1r), which gives an indication of the manuscript’s date of origin. As many other manuscripts from religious institutions, this manuscript came into the possession of the Jesuit College of Porrentruy during the French Revolution, until in the 20th century it became part of the collection of the Library of the Canton of Jura.
